Graphing Calculator Draws Itself Up To 3.0 -- Back in 1994, when Apple released the first Power Macs, an elegant little application called Graphing Calculator helped wow the mathematically inclined masses by quickly graphing and smoothly animating graphs of mathematical equations. 10 million copies of Graphing Calculator 1.0 and 1.1 shipped with Macs, but the developers of Graphing Calculator also struck out their own and continued to improve the program and sell it commercially. It's proven popular in education, and even for those who don't need its graphing capabilities, Graphing Calculator remains powerful and helpful for use with normal day-to-day calculations. With version 3.0, Pacific Tech has added significant enhancements, including support for saving and opening Graphing Calculator documents, text comments in documents, multiple document windows, save to HTML (with PNG graphics), and export to RTF for import into word processors. Graphing Calculator costs $60, or $40 for students, and there are a variety of upgrade prices, depending on your situation. If you just want to get your feet wet with Graphing Calculator, the versions Apple shipped are still available for free. Graphing Calculator is definitely worth a look for anyone who works with equations, and even if you don't, Graphing Calculator still makes for a slick demo. [ACE]
Find Text Leading from Acrobat PDF
Ever have to recreate a document from an Acrobat PDF? You can find out most everything about the text by using the Object Inspector, except the leading. Well, here's a cheesy way to figure it out. Open the PDF in Illustrator (you just need one page). Release any and all clipping masks. Draw a guide at the baseline of the first line of text, and one on the line below. Now, Option-drag the first line to make a copy, and position it exactly next to the original first line at baseline. Then put a return anywhere in the copied line. Now adjust leading of the copied lines, so that the second line of copy rests on the baseline of the second line of the original. Now you know your leading.
Or you could buy expensive software to find the leading. Your choice.
